1 Claim.

This invention relates to rail frogs such as are used in places where one rail crosses another.

In the passage of train wheels over rails, such a frog is apt to be accompanied by bumps and shocks and it is the principal object of the present invention to provide a novel construction of rail frog whereby much of the shock will be eliminated.

Such frogs are frequently used on main lines of railroads where a switch rail or crossing rail crosses one of the main line rails.

A second important object of the invention is to provide a novel construction of rail frog whereby a car wheel, running on the main line rail may pass the intersecting rail with no appreciable shock.

A third important object of the invention is to provide a novel arrangement of rail frog wherein the main rail is provided with a hinged and shiftable section automatically movable out of alinement with the main rail to permit passage of a wheel along the intersecting rail.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a planview of a rail frog constructed in accordance with this invention;

Figure 2 illustrates a horizontal section through the web portions of this free; and

Figure 3 illustrates a detail plan of a certain main line section used in this invention.

In the invention as here shown, the frog is provided with an intersecting rail portion indicated in general at In and having the usual head I 1, web I2 and foot l3. This portion i is formed as a continuous rail length and has a main line rail portion I4 welded thereto on one side at an acute angle as at I5. The rail portion I4 is likewise provided with the usual head 16, web I! and foot I8. A wheel flange receiving notch I9 is provided in the head II on the flange side of the head l6 as shown in Fig. 1. Alined with the section I4 is a main line section 20 having a portion of its head 2|, web 22 and foot 23 cut away as indicated at 24 so as to leave a projecting portion of its foot to form a tongue 25 welded to the foot l3 at the wheel flange side of the rail section II]. A movable section 26, v-shaped in plan, is formed to proand web 29 and a half foot 30. This portion is normally alined with the section 20, that is the head 28 is alined with the heads l6 and 2! and spans the gap between the two. Also the web 29 is normally alined with the web 22. The flange 30 of this portion forms a complement of the tongue 25. The section 26 also has a guard portion 3| which has a half-head 32, a web 33 and a foot 34, the head 32 normally resting against the wheel flange side of the head I I.

In order to hold the portion 21 in to the rail section 20, the Webs 22 and 29 are connected by a strong hinge 35. Adjacent the bend of the secend of the cap member 39.

wide a. main line portion 21 having a full head 28 tion 26 is a slot 3 6 and a tubular boss 3'! extends outwardly from the section 26 in alinement with the slot. Fixed to the web [2 is a rod 38 which extends through the slot 36 and boss 31 and also extends through the end' of a cap member 39 where it is provided with a nut 40. A spring 4| surrounds the rod 38 between the boss 31 and the A V-shaped guard rail member 42 is fixed in the angle between the section 26 and the section III and a guard rail 43 is also fixed in the angle between the sections l0 and I4 alongside the latter at the wheel flange side thereof. From the foregoing it will be seen that a wheel on the main line ra il will pass smoothly between the sections 14 and 20 because of the interposition of the portion 27 but that a wheel on the intersecting rail section ID will be able to pass by moving the section outwardly as shown in dotted lines in Fig. 1, the spring 4| restoring the section 26 to normal position as soon as the last mentioned wheel has passed.

I claim:

In a railway frog, a rail structure comprising an intersecting line section and having a main line rail section fixed to and extending therefrom at.

one side thereof, a second main line section alined with the first main line section on the opposite side of the intersecting rail section containing the main line rail section, the main line sections having heads, the head of the second main line being spaced from the intersecting rail section, a filler section having a head normally filling the space between the heads of the main line section, a hinge connecting the second main line to said filler section, and spring means yieldably holding said filler section in normal position filling the space between the heads of the main line section, said filler section having an angular extension extending along said intersecting rail section and provided with rounded end faces at the side adjacent th intersecting rail section.
